The effect of tool rotational and traverse speed on friction stir weldability of AISI 430 ferritic stainless steels
Highlights ► The best mechanical resistance values were obtained at tool rotational speed of 1120min−1 through five tool rotational speeds (560,710,900,1120,1400). ► The best mechanical resistance values were obtained at traverse speed of 125mm/min through five travel speeds (80–200). ► Notch impact energy decreases with increasing the tool rotational speed. ► Notch impact energy increases by increasing the traverse speed.
Abstract In this study, the effects of tool rotational speed and traverse speed on welding of AISI 430 (X6Cr17, material number 1.4016) ferritic stainless steels by friction stir welding method are examined. Two specimens with dimension of 3×100×200mm were joined in butt position. Tool rotational speeds were determined to be 560–1400min−1 and traverse speeds as 80–200mm/min. During the studies, tool pressure force 3.5kN and tool angle of 0° was kept constant. Hard metal carbide (WC-Co hard metal identified as K10) with equilateral triangle tip profile was used as the tool material. Determination of the tool advance speeds related to the tool rotation speeds giving the best-looking weld seals with acceptable values of mechanical properties was aimed. During welding of the specimens joined in butt position, the temperature change due to time and variation of the pressure force applied on welded specimens by the tool shoulder has been recorded. It has been observed that the best mechanical resistance values were obtained at tool rotational speed of 1120min−1 through five tool rotational speeds (560–1400). Also it has been observed that the best mechanical resistance values were obtained at traverse speed of 125mm/min through five traverse speeds (80–200) with the constant tool pressure force of 3.5kN and tool angle of 0°.
